This could sounds as Tiamat's The Astral Sleep/Clouds copycat, but it is not. The atmospheric Death Doom band Aeon Aphelion displays atmospheric music that conjures up visions of the past in a typically greek way (think Nightfall, Rotting Christ etc....)
The band however took a more traditional-sounding turn on their first full-length album, crafting a personal, rather harsh kind of Doom.
